Agenda Item: Welcome and Unfinished Business
from Day One, Ms. Sherry Drew, Chair
MS. DREW: Good morning. Welcome to our meeting.
We reported the number of Commissioners that were here
yesterday. We are all here again today, other than
Michelle Williams, who will be slightly late. I am
wondering if we have any unfinished business from yesterday
that anyone would like to raise.
There being no unfinished business, we will move
onto Dr. Rosemary Johann-Liang, DVIC, Clinical Update on
the Institute of Medicine Report, Generated Task Force
Update.
Agenda Item: DVIC Clinical Update/Institute of
Medicine Report Generated Task Force Update, Dr. Rosemary
Johann-Liang, chief Medical Officer, DVIC
DR. JOHANN-LIANG: Good morning everybody. The
way the agenda has it s that I’m going to be talking about
IOM and other folks will be talking about rotavirus. We’re
going to be actually doing this all together.
You know, when we usually do the every three
month update, I give you guys a quarterly update on the
medical review and analysis, going over how many claims
came in, what the claims were about, what were the
vaccines, some interesting issues, et cetera.
2
But because we have an hour and a lot of slides
to cover, and some thinking involved this morning, I am
going to just do that next time, and we’ll bring it
together and give you guys an updated review of the medical
update. Today I want to just give you a brief update on
the IOM report.
Remember, last ACCV, when you guys met, Dr.
Clayton, the Chair for the IOM Committee, gave you guys a
full briefing on the report. I believe everybody received,
the ACCV members, and I know we have new members, so we’ve
got to get, Annie, we’ve got to get the pre-pub copy to
them as well. We have ordered the IOM hard copy. It
comes in a book for all of you at the ACCV.
But they apparently take a long time going
through their editing and copying thing and going to
wherever the books go to get bound, et cetera. And so it
probably will be some time in the spring that those books
will be available for everyone. So we’ll make sure that
everyone has a pre-pub copy available. That’s what we are
working off as well for now until we have the full
publication available.
I am going to just give you a little bit of a
background, because we have some new members joining, and
then give you an update of where we are with this. And
then the most of this hour we want to spend on the
3
rotavirus vaccine and intussusception and proposal for
changes to the injury table.
I am going to be doing that with my colleagues
from the rotavirus Vaccine Working Group. As it turned
out, we really did not plan this, we are all in sort of
black and red today. So you can see that we’re all
synchronized in our thinking. It’s government at its best.
The members from the working group who will be
speaking today will be Ms. Anna Jacobs. She is our Office
of General Counsel, Counsel to our VICP, and member of our
working group. And Dr. Mary Rubin, who is a pediatrician
and one of the medical officers in our division.
So let’s just talk about IOM vaccine adverse
event review history. The contract actually to the IOM
started in the fall and the winter of 2008. It took some
time to get all the paperwork in order for them to look for
the committee members that would be totally no conflict of
interest, et cetera.
And so it took until April of 2009 for us to meet
the committee, the initial committee, and give them the
charge from the government as to what we would like for
them to do. And really, this was the first time, I think,
it was a HRSA-generated IOM contract.
There were a number of vaccines that had been
added to the table that had no adverse events listed on
4
them. Our goal was to really try to get an outside
independent assessment of the current science so that we
can update the injury table.
And to do so, we asked them not only to look at
certain vaccines and certain adverse events, but to really
give us some sort of a framework of doing causality
assessments, because there are many different ways people
look at causality, but it was really important for us to
all work by the same sort of framework.
And even after IOM was done, there are other
vaccines that we just couldn’t ask them to review, because
there are only limited funds. So we would need to go back
and do some of that causality assessment for other
vaccines, other adverse events. We really wanted to know
what framework to work off of. That was a really major
issue.
But then we also gave them a list of adverse
events that really were generated by us talking to our
sister agencies throughout the government, especially CDC,
the Immunization Safety Office, where we are currently
working with.
The list of adverse events was generated for four
vaccines initially. Mainly the criteria for why those four
out of the 16 that we have covered in the program, is
because those were ones that were newer, that did not have
5
adverse events listed. And then thirdly, really, the
vaccines that had a lot of claims coming into our program
and there was media attention.
So the initial ones were really varicella, which
was added a long time ago, but there was nothing listed on
the table, influenza, which was a big vaccine in the sense
that we were getting a lot of claims, meningococcal and
HPV, because these were newer vaccines. That’s all we had
resources for.
And then thankfully, after the initial charge
went out we were able to get additional funding through the
ARRA stimulus funding through CDC, and add four more
vaccines for review. And this was really fortuitous
because it only needed a little bit of resources to add
more vaccines, because the sitting of the committee is what
was so costly.
And then after all of that, the final release of
the report was this August. You all heard the presentation
by the Chair in the last ACCV. So these were the vaccines
that were reviewed. And they were reviewed together. It
shows that it really makes up 92 percent of VCIP claims.
So we thought that was really helpful for us to get a good
sense of how we can go and modify the Vaccine Injury Table.
Remember that the working list of adverse events
were generated from our staff, based upon our statistics,
6
and what the current science as we understood they were.
And then we presented it publicly during the charge, and
IOM put the working list up on their website, so it was
open to the public. And the public had all of that time to
add their comments and their recommendations to the list.
The IOM was not going to take away anything that
we had asked for, but they were open to, and they did, add
further adverse events to the list. And because this is
really supposed to be an independent review by them, we
gave them a general concept. It was really up to them to
figure out the framework and how they were going to put the
adverse events together, and what the final list and the
final review was going to be.
As you saw from the report, the final working
list constituted 76 different adverse events, 157 adverse
event vaccine combinations. So as you saw on the report,
they had the causality framework as we asked them, as we
charged them, with a three-pronged approach. They looked
at not only the weight of the epidemiologic evidence, at
the four levels, but also the weight of the mechanistic
evidence, and they put that together for an overall
causality assessment.
And the conclusions that they had also were in
four different categories, and it lists here what
convincingly supports, what favors acceptance, what is
7
inadequate to accept or reject, and then what favors
rejection. Those were causality conclusions. We will
really spend a lot more time on this once we bring what our
thoughts are, based upon their review, before you.
Currently, the members of the HHS, the Task Force
for this, which constitutes Immunization Safety Office, our
Office of General Counsel and HRSA reviewers, are working
very hard. So everything is under review. Our goal is, at
the risk of being called a taskmaster, our goal is to
really try to at least bring the initial thoughts before
you for the next ACCV meeting.
The nine working groups –- it is the eight
vaccines, but we also have a general category which we
charge the IOM for, which is the actual injection and
administration adverse events. That is the ninth category,
and that is what we are all very, very busy working on
right now.
I’m going to just move right along unless
somebody has a burning question about the first part of
this. So rotavirus -- I’m going to actually ask my
speakers here to come up and join me, and then we can do
this as a team. This is Anna Jacobs and Mary Rubin, and we
are going to be talking to you about rotavirus vaccines and
intussusception.
8
Agenda Item: Intussusception: Proposal to Add to
the Vaccine Injury Table for rotavirus Vaccines, Ms. Anna
Jacobs, Office of General Counsel
DR. JOHANN-LIANG: Now this is something you have
heard a lot of, because we have kept you abreast as we have
learned things too, as to what we are doing. But we have
come to a time where we are actually going to ask you what
your thoughts are.
I want to make sure that all of you in your
binders have not only the slide set but the proposed reg.
Do you have all that? And the voting folks are eight, and
Michelle, nine, right? So if you can make sure that you
have the regs with you. It is the one that looks like a
lawyerly kind of thing. It has the table, it has a little
blurb and there is a table. It is really important that
you guys all have the regs with you.
So the IOM did not include –- we did not ask them
to include the rotavirus because at the time when we gave
the charge, rotavirus issues were pretty quiet. So we only
could ask them to get the big ticket items at that time.
But as the IOM review was ongoing, we had some
recent post-marketing surveillance publication come up,
which led us to establish our rotavirus working group and
the intussusception issue. And today we are finally
proposing a draft regulation regarding this adverse event.
9
So these are the members of our working group.
Dr. Shaer is sitting here as well. And Dr. Smith, I
believe is on an open line. Remember, she is the one that
gave you guys a very comprehensive talk on rotavirus and
all of that data, preclinical, the thoughts about the
shedding and all that which we don’t have time to go into
today. I am just going to briefly just give you a summary
so that we can all come to speed.
The outline is that Anna Jacobs is going to give
you some of our legal history and what ACCV came up with
some years ago, the Guiding Principles about how we go
about changing the Vaccine Injury Table.
I will summarize some of the data because that
has already been extensively discussed. And then Dr. Rubin
will talk about there is an ongoing study in the US right
now that I think it is important that you guys know that
that is ongoing. And then the actual proposed changes to
the table. I will come back, summarize and ask you guys
what your thoughts are.
We may need a little bit of a -– this is a really
good practice going into the IOM. We may need to figure
out a little process issue of how we are going to query the
members for their input.
rotavirus disease, just to start off, is very
common. I am sure that if you have young children, most
10
young children have rotavirus. In the winter months is
when it comes the most. They have vomiting, fever,
gastroenteritis, and almost everyone gets this by age five.
The mortality is not such an issue in the US, but
in developing countries there are many deaths actually
caused from this due to dehydration, et cetera. And even
in the US there are many rotavirus induced, disease-induced
hospitalizations. Although now with the vaccinations in
place the hospitalizations are decreasing.
Then, talking about what intussusception is, the
picture is worth a thousand words, right? It shows you how
one segment of the bowel sometimes, for various reasons,
actually sort of telescopes into the next segment of the
bowel. You can imagine all those blood vessels sort of get
pulled with it. And so you start to get less blood flow,
and then swelling of the gut. And then eventually you will
actually get obstruction and the child can really get into
trouble.
It is quite uncommon, the intussusception part.
It is about 1,400 kids in the US per year. Just so that we
can have a common denominator for you to put things into
context, that translates to something in the US on the
order of like 30 to 60 cases per 100,000 kids per year.
PARTICIPANT: That’s pre-rotavirus. That’s just
the baseline incidence.
11
DR. JOHANN-LIANG: This is background, background
incidence of intussusception, so just so that you can put
it in the context of intussusception, what the numbers look
like when you have the RotaShield, which Anna is going to
talk about. And then I will come back and talk about what
the numbers are with the second generation rotavirus
vaccines, because I think it’s important for you guys to
know the magnitude of the issue.
So you don’t really see this too much in little,
little babies. It really sort of starts to peak about,
earliest maybe at two months, and it goes up to peak at
like six months. You can have intussusception even in an
older child, but the peak really is that the babies, when
they are really cute, you know that four to six months,
that time. It is really pathetic when they -–
So naturally occurring -- there is a little bit
more information. So this is intussusception as a
baseline. It is interesting that this adverse event really
varies by region. For example, you are going to see the
new study that was published in Mexico and South America.
Even as a background, in South America the incidence of
this adverse event, intussusception, is much higher, on the
order of doubling what we see in the US.
So there are region variances. And Mary is going
to talk about all the different issues of why IS occurs
12
naturally, without the vaccine. It is usually diagnosed
with, if you have stool that is we call currant jelly
stool, you have the diagnostic thing right there
clinically.
But sometimes you need to use radiological tests
to diagnose it, which we do with the barium contrast. But
also just putting the barium through sometimes reduces and
actually corrects for the intussusception. That is
different than children who actually end up having surgical
intervention.
It seems that the data shows it really is not
that there is any difference between these kids. But if
you don’t treat or reduce the telescoping with the barium
or by natural happenstance –- I remember having a patient,
getting them through the ambulance. We hit a pothole –-
boom, the pothole hit, the kid reduced. So you can have a
natural reduction. But usually you need a barium
reduction.
But if you don’t get to the child, and you end up
-- yes, I got a standing ovation when I got off the
ambulance -– but when you don’t get to reducing them, then
they can go on in their disease. And you can see that the
more you obstruct, it just becomes to a point where the
child has to undergo surgery, and the surgical
intervention.
13
So that is the different way to treat it. It
looks like it’s about 50/50 in how the patients get treated
with this illness. So morbidity and mortality from this
adverse event is very low in the US, just like rotavirus
mortality is very low in the US. And recurrences do
happen. I am going to turn now over to my colleague here.
MS. JACOBS: I am Anna Jacobs, and I am an
attorney with the Office of the General Counsel, and I
advise the VICP with Elizabeth Saindon, my colleague.
Today I will just go over again the basics of the Vaccine
Injury Table and how that is revised and what your role is
in all of this. And then we will walk through the history
of rotavirus as it relates to the table and the program.
So as you are well aware, the program has a
Vaccine Injury Table, and claims that fit within the
parameters of the table receive a presumption that the
vaccine caused the injury. And the petitioner is entitled
to compensation unless the government can prove that
something else caused the injury.
And so if the claim does not fit within the
parameters of the table, then the petitioner can receive
compensation if he or she proves that the vaccine did in
fact cause the injury.
And so how do you fit within the parameters of
the table? The petitioner has to prove three things. The
14
petitioner has to prove that she received a vaccine set
forth in the table, sustained or significantly aggravated
an injury listed on the table in association with that
vaccine, and sustained the injury, or the onset of the
injury occurred within a time frame listed on the table.
And so the injuries are defined in a section that
is called the qualifications and aids to interpretation.
And the statute says the following qualifications and aids
to interpretation shall apply to the Vaccine Injury Table.
We also call them the QAI.
And so Congress recognized that science is not
static. It changes. And so they wanted the table to also
be able to change along with science. But they didn’t want
to leave that up to the legislative process because the
legislative process moves a lot slower than science does.
So they gave the Secretary the authority to change the
table by way of the regulatory process.
So by regulation, the Secretary can modify the
table by adding or deleting vaccines, adding, deleting or
modifying injuries. And that includes the definitions of
those injuries. And can also change the time periods
listed and add those.
And that regulatory table is found in the Code of
Federal Regulations in Title 42 in Part 100.3(a). And so
by statute modifications to the table apply only with
15
regard to petitions that are filed after the revision.
Just to go through the general basic process of
the regulatory process, basically, the Secretary would
publish a Notice of Proposed Rulemaking, and then the
Secretary would have to afford at least 180 days of public
comment and provide a public hearing on the proposal. And
then after that period closes the Secretary can move
forward with publishing a final regulation.
What is your role in all of this? The Secretary
cannot propose a regulation until she first provides you
with a copy of the proposed reg text, which is what you
have before you in your materials, and requests comments
and recommendations, and affords you at least 90 days to
come up with a recommendation.
So what standard should guide you in considering
the proposal? Unfortunately, there isn’t a whole lot set
out in the statute. The statute does give a standard for
when the Secretary should add a vaccine to the table. And
the Secretary should do that when the CDC recommends a
vaccine for routine use in children, the Secretary shall
add that vaccine to the table within two years. But there
is no standard for adding injuries, modifying or deleting
injuries.
And so, in 2006, the ACCV at that time developed
a set of Guiding Principles. And I believe you also have
16
this document in your materials, and you are welcome to
pull that out. I am going to just walk through them and
summarize them for you. I should say these principles are
not legally binding on you. They are just helpful, it’s a
helpful set of guidelines that you are welcome to use.
So in essence, the ACCV then believe that the
table should be scientifically and medically credible, and
where there is credible scientific and medical evidence,
both to support and reject a proposed change, then the
change should really tend toward benefiting the
petitioners.
So what is scientifically and medically credible?
The ACCV said that conclusions in IOM reports are deemed to
be credible, but of course that should not limit your
discussions. For data sources other than IOM reports, you
will need to assess the relative strength of the evidence.
Consistency across multiple sources is an indication of
strength of the evidence.
And so they set out a hierarchy of data sources
ranging from the strongest sources to the weakest sources.
And I won’t go through all of them, but the strongest
sources are going to be the clinical laboratory data,
challenge/re-challenge data involving non-relapsing
symptoms or diseases in controlled clinical trials. And
the weakest source is going to be more like your case
17
reports, editorial articles on scientific presentations and
non-peer reviewed publications.
And also consider whether there are
methodological limitations in the studies, is there any
potential bias or confounding factors, and is there
biologic adherence in the conclusions.
Do not worry, though, if you are not a scientist
and you don’t regularly assess the strength of evidence,
because you are welcome to seek the assistance from the
Division of Vaccine Injury Compensation. And you can ask
them to guide you through the evidence to help you assess
the strength.
And of course, the ACCV recommended that you
should remain aware of the policy considerations underlying
the table. Congress basically intended that awards to
vaccine injured persons should be made quickly, easily,
with certainty and generosity. And they also intended to
compensate the very serious injuries. And so if there is a
perfect split down the middle in the evidence, then you
should tend toward adding or retaining the injury.
So now I’m going to walk through the history of
rotavirus in the program as it relates to the table.
Rotavirus vaccine is not new. On August 31, 1998, the FDA
licensed the live, oral, rhesus-based rotavirus vaccine,
and that was under the trade name of RotaShield. This was
18
the only US-licensed rotavirus vaccine on the market at
that time.
And so the CDC then recommended this vaccine be
routinely administered to children, and so on October 22,
1998, the Secretary added the general category of rotavirus
vaccine to the table, with no condition specified, or no
timeframe. So around this time, VAERS had been receiving
reports of intussusceptions occurring after the first dose
in infants.
So July 16, 1999, the CDC then recommended that
parents and health care providers suspend the use of
RotaShield, and they continued to conduct studies to
determine an association. And the manufacturer voluntarily
ceased distribution of RotaShield. And then on October 15,
1999, they voluntarily withdrew the vaccine from the market
and requested immediate return of all doses.
Shortly after that, October 22, 1999, the ACIP
concluded that intussusceptions occurred with significantly
increased frequency in the first 14 days following the
administration of RotaShield, and withdrew their
recommendation for use of RotaShield in infants, and the
CDC adopted that as their recommendation.
And so in 2001, July 13, the Secretary published
a Notice of Proposed Rulemaking to revise the table. And
the Secretary found that intussusceptions could reasonably
19
be determined in some circumstances to be caused by
vaccines containing live, oral, rhesus-based rotavirus.
The Secretary proposed to add a specific category
of vaccines containing live, oral, rhesus-based rotavirus,
with the associated injury of intussusception with a
timeframe of zero to 30 days. The Secretary then published
the final rule on January 25, 2002, and it became effective
on August 26, 2002.
And so basically, what the table then looked like
was, there was this general category of rotavirus vaccines,
no conditions specified and no time frame. And there was
also this specific category of live, oral, rhesus-based
rotavirus vaccine with injury of intussusception, with a
timeframe of zero to 30 days.
And that injury only applied to vaccines
administered on or before the effective date of the
regulation. And you will recall, though, that the vaccines
had been long since withdrawn from the market, and they
weren’t being distributed.
So if you fast forward then to October 9, 2008,
the Secretary removed then the specific category of
vaccines containing live, oral, rhesus-based rotavirus and
the associated injury. And her reasoning for this was that
RotaShield was removed from the market on October 15, 1999,
and the CDC withdrew their recommendation for routine use
20
of the vaccine shortly after that.
So really the claims could likely only been for
injuries sustained from vaccines that were administered
before that time, because they were not being administered
after that time.
So if you take that into consideration, and the
fact that the table required the injury to have occurred
within 30 days after the vaccination, and you consider the
statute of limitations, which in the case of table
revisions, for injuries that occurred before the revision,
the petitioner has two years to file a claim, and the onset
of the injury needed to have occurred within eight years
preceding the revision.
So doing the math, if the date of table revision
was August 26, 2002, then the date that the last claim
could have been filed would have been August 26, 2004. And
the onset of injury or the death needed to have occurred
between August 26, 1994 and August 26, 2002.
But that filing deadline of August 26, 2004 is
the key date. And so by 2008, the Secretary believed that
any potential claim under this specific table category
would have been time barred. But the Secretary did retain
the general category of rotavirus vaccine with no condition
specified, no timeframe.
And that is where we are today. And I will turn
21
the platform over to my colleague, Ro.
DR. JOHANN-LIANG: Ro needs to speak very fast
because we are in a time crunch here. This is a slide that
you all saw already. I believe this was given to you –
update 3/20/11, it must have been in March. I say it right
up there on the slide here. March you got this slide. And
what I tried to do here was, because you did get an
extensive review from, I believe, the FDA representative in
October 2010, when all of this was being presented to ACIP.
I just did a summary slide for you at that time,
showing what the difference between the RV1 and RV5 is, and
then what pre-licensure studies showed. So the way the
pre-licensure studies for these second generation vaccines
were powered, the numbers needed was based upon what they
saw with RotaShield.
If the RotaShield was -– if they thought there
was maybe one in 11,000 they wanted to rule that out, and
that is why it was powered to have about 30,000, 35,000.
That is a huge safety study. As a pre-licensure study
goes, you just don’t see that, and that is why you see the
numbers like that. And really, there was nothing seen, so
it was ruled out for IS, for intussusception.
And the post marketing, remember, you have seen
all this before, and I’m going to go over this again. But
this is what was shown to you in March as a summary slide,
22
and then in June, the New England Journal publication came
out about the South American studies.
And what they showed was a slight increase in
attributable, meaning there is a background. And remember
I told you, there’s more of intussusception down in South
America. But on top of that, they also thought there was a
little bit of an attributable risk from the vaccination,
mainly with the first dose, one to seven days post the
first dose.
And there was a commentary also written about
this, talking about the background of RotaShield. Really,
for safety we look at the totality of the evidence, all the
different things, the background, what is happening. It is
kind of like that kind of editorial.
So given this coming out in June, this is a
further updated slide of what you saw before. And I just
took out the pre-licensure and expanded on the post
marketing a little bit. So that study, the Patel, et al,
from the New England Journal, was Mexico, the incidence
rate of 5.3, one to seven days after first dose, not after
dose two.
In Brazil a little bit different. And Dr. Smith
went through this with you last time. It was actually
after dose two, not after dose one. Again, one to seven
days after the vaccine. And the thought behind it, nobody
23
really knows but the thought behind that is that in Brazil
oral polio is co-administered. And the thinking was that
the oral polio -- and I guess what is happening in your gut
may take precedence over what needs to happen
immunologically for rotavirus vaccine.
So it is not really until dose two that you see
this effect, that small attributable risk on top of -- and
then also for Rotarix. And when we talk about Rotarix
right now, there is the Australian surveillance which
looked at what was happening with the kids against the
expected. So it is not a concurrent control, it is really
an expected number.
And they did a relative risk and then again saw
something a little bit above one to seven days post after
first dose, and not after second dose. That is Rotarix.
RotaTeq, the data is even not -- the issue is, Rotarix is
where we have better data. I think there is a little bit
of an attributable risk.
It is really in the order. If you think about it
like this. So baseline is something like 30 to 60 in the
US per 100,000. So the RotaShield was really like an
additional five to 10 cases per 100,000. For these second
generation vaccines, very simply, probably if there was
something there, something in the order of one or two extra
cases per 100,000.
24
We are talking about much lower magnitude of
attributable risk. But it looks like for Rotarix, because
you have seen it in a couple of different places outside of
the US data, that something is really there. RotaTeq is a
little bit difficult because the only thing we really have
is the article by Buttery et al. in Vaccine that talks
about, again, the Australian data.
We don’t really have anything that is what we
call a positive study in the sense of an attributable risk
in the US at all. And RotaTeq is actually the vaccine that
is being most utilized in the US. Now I am told by CDC
that Rotarix will have an uptake, and we will see Rotarix
use in the US as well, moving into the future. But
currently it is really RotaTeq that we use in this country.
Dr. Rubin is going to talk about because of this,
because this is uncertain data sets and there is really
nothing in the US, the FDA has started a study on this
issue. And she will talk about this.
DR. RUBIN: Good morning, everybody. Again, my
name is Mary Rubin and I am a pediatrician. And I work as
a medical reviewer at DVIC. I know the important thing is
the proposal, but I will first discuss the ongoing study
which is part of the FDA’s Postlicensure Rapid Immunization
Safety Monitoring program, which is PRISM.
PRISM was actually established as one of the
25
several 2009 H1 influenza vaccine safety surveillance
efforts. And then PRISM was incorporated into the mini
Sentinel to focus primarily on vaccines. The mini-sentinel
is one piece of the Sentinel Initiative, which is a multi-
faceted effort by the FDA to develop a national electronic
system that will complement existing methods of safety
surveillance.
So this PRISM study on rotavirus vaccines in the
US will assess the risk of intussusception after Rotarix
and/or RotaTeq vaccines. So this is actually both the
second generation rotavirus vaccines.
Now a detailed protocol is found in the mini-
sentinel website, which is on www.mini-sentinel.org, for
those people on the phone. It is also on the slide set.
This analysis will use what is usually used in the Vaccine
Safety Datalink studies. Self-controlled, case centered
and sequential methods. And the total study population is
estimated to be greater than one million infants, during a
maximum study period of January 2004 to a point in 2011
that is undetermined
The investigators are hopeful to have preliminary
results by the fall of 2012. So this data is not available
to us right now. But based on the available data, which I
will go back to Dr. Johann-Liang’s slide, as you can see
the increased rate of rotavirus intussusception, there is a
26
small increased rate within one to seven days after the
first dose. And most of the data that is available is with
Rotarix vaccines.
So we will go back to our proposal. We do
propose amendment to the general category of rotavirus-
containing vaccines, which involves the injury of
intussusception, with a time period of zero to 21 days.
Now as the publications show, one to seven days is the risk
window. And we are proposing zero to 21 days, to be
consistent with the ACCV Guiding Principles. As Ms. Jacobs
mentioned earlier, RotaShield intussusception data showed a
one to 14 days window. And the Vaccine Injury Table listed
zero to 30 days for that rotavirus vaccine.
So what is intussusception? I know you have
heard a lot about it already. But intussusception, as
Rosemary, Dr. Johann-Liang mentioned, is the invagination
or telescoping of the proximal segment of an intestine into
the distal segment of the intestine. This can result in
obstruction of the bowel passage, constriction of the
mesentery and obstruction of the venous blood flow.
This can be characterized by sudden onset
abdominal pain. As Ms. Jacobs mentioned, there is a
section in the Code of Federal Regulations, that the
following Qualifications and Aids to Interpretation shall
apply to the Vaccine Injury Table, to paragraph A of the
27
section and Code. So we are proposing to add this
paragraph that defines the injury of intussusception.
This slide is actually just a snapshot of the
specific Vaccine Injury Table line. But you have the full
Vaccine Injury Table with the regs in your handouts. So it
just shows the vaccines containing rotavirus and injury
intussusception in zero to 21 days.
Now in addition, the proposed paragraph for
Qualifications and Aids to Interpretation, or QAI, as I
will call it from now, gives presumption of causation to
intussusception occurring after the first or second dose.
As publications show, association after the first dose.
And actually, some of the studies of RotaTeq show that the
third dose is protective, or does decrease risk, and in the
absence of alternate factors.
Now while in most intussusceptions, the cause is
unknown, a proportion of naturally-occurring
intussusceptions have been associated with infectious
disease, conditions causing lead points, anatomic
abnormalities and underlying conditions or systemic
diseases.
I will discuss each of these factors in a little
more detail in the following slides. And for each section
you will find references to articles of medical literature.
The credits go to Dr. Chris Liacouras, who is the Pediatric
28
Gastroenterologist from the Children’s Hospital of
Philadelphia, for literature review and reference.
So infectious disease secondary to both enteric
and nonenteric strains of adenovirus enterovirus, and other
viruses are linked to intussusception, as well as bacterial
enteritis such as those due to campylobacter or salmonella
typhi, as well as parasitic diseases such as ascaris, could
be examples.
Intestinal masses like polyps and tumors and
cystic structures like Meckel’s diverticulum and
duplication cysts, and also increased lymphoid tissues such
as lymphoma, may actually protrude into the intestine, or
create a weakness in the wall. So these can act as what is
called lead point, which causes the intussusception.
And then congenital anatomic abnormalities such
as malrotation, anatomic changes after surgery, and
abnormal intestinal blood vessels such as hematoma or
hemangiomas are also attributable factors.
Finally, systemic illnesses such as inflammatory
bowel disease, namely Crohn’s Disease and ulcerative
colitis, also cystic fibrosis and celiac disease have been
associated with intussusception. As an example, in cystic
fibrosis the stools in these patients can become very
dehydrated and putty like in consistency, and adhere to the
bowel wall. And this actually can act as a lead point.
29
Also, there are other conditions that have small
vessel tissue inflammation, which have been associated with
intussusception as well, such as Henoch-Schonlein purpura
and Kawasaki disease. So putting all of these together,
here is a slide of the proposed language of the QAI, which
you also have in your handout. I guess I will stop here.
DR. JOHANN-LIANG: You guys all have this in
front of you? This is the Qualifications and Aids at the
bottom of the proposed regulation change. And basically
Dr. Rubin just went over the definition of intussusception.
And that is followed by, basically this is laid out as what
really doesn’t qualify to give you presumption of causation
under the table if you have a baby with an intussusception.
So that is what you have before you.
I am just going to go on to just give you an
update. I gave you an update about so what does it mean
for our program really, to kind of put that in perspective.
The last time we met I believe I gave you a brief synopsis
of 12 cases that we had gotten claims for. That number is
up to 15 now, at the end of fiscal year 2011. These were
15 RotaTeq intussusception claims.
And this is sort of a demographic breakdown, 11
males, four females, age range from eight to 31 weeks, and
you can see that these are all you would see in the
background IS population. And it breaks down really, there
30
are five after dose one, five after dose two, and five
after dose three. That is how it broke down.
And many of these children really did have
serious sequelae in the sense that they ended up in the
hospital and had to actually undergo surgery. Eighty
percent actually have surgical intervention, not just
barium enema. And about half of them had -- if you look at
the listings in the QAI that Dr. Rubin was going over --
about 50 percent of those kids actually had one of those
qualifications for alternate factors. That is kind of what
we have.
So this is not by any means the flu generated
claims that we see. This is a small percentage of what we
are reviewing in the program. But certainly given the new
information, and under really the Guiding Principles that
Ms. Jacobs went over, we really felt that we wanted to
proactively bring this before you and propose a regulation
change.
So in summary, some but not all studies suggest
the possible very low risk of intussusception caused by the
second generation rotavirus vaccines, mainly the studies on
Rotarix. And it is after the first dose, within the one to
seven days post-window.
The level of observed risk, I talked about the
numbers with you and sort of gave you a side by side
31
comparison background to what we saw on RotaShield and what
we are seeing with the second generation rotavirus
vaccines. And possibly, if there really was an
attributable risk, there will be an additional one case per
100,000 infants.
We do know that the benefits continue to outweigh
the risk, and so the rotavirus vaccines are still being
recommended by CDC, by ACIP. It is a very different story
than what RotaShield attributable risk was shown at that
time in the history you heard from Ms. Jacobs.
So given, as I said, the background of the
RotaShield experience that we had in intussusception, given
the new intussusception information, mainly coming from
literature inside of the United States, but given that we
have the Guiding Principles which you already have, this is
what we are proposing.
Keep in mind, though, as Dr. Rubin went over,
there is a study that is ongoing right now, and it is a US
study, the PRISM study. So we don’t know what the answers
are to that yet. That’s an unknown. We also gave you the
hard copy of the proposed regulation changes, because that
is what the statute requires for the ACCV members to have.
And we also are asking you for your recommendation.
And the choices are as follows as to what we want
to do with the proposed regulation. You can concur with
32
the proposed amendment to the table. And what that would
mean is that we would bring together a Notice for Proposed
Rulemaking, NPRM, which we have already started to draft.
And we have to get that out to the public. There will be a
six-month comment period for the public to give their
input, and then we can move ahead to a final rule. That is
what number one is.
Number two is that you don’t concur with the
proposed amendment and you don’t want to move forward, you
don’t think there is enough evidence here, you think that
the numbers of claims coming into the program are not that
much. I don’t know what your reasons are, but that would
be one choice.
Number three would be you have the regulation in
front of you and you want to think about it, sleep on it,
and you want to make recommendations to changes for the
next meeting. That’s a choice.
And number four, because we have this US PRISM
study that is ongoing right now, that you would like for us
to wait until the data from that study is final. Which we
think that at best the preliminary answers will be end of
next year, 2012, and then the final answers probably won’t
be until sometime in 2013. It takes forever for the end
product of publications to come out. I don’t know, it
depends. But it’s some time to go. But that is a choice
33
you have.
Keep also in mind that from the summary that Dr.
Rubin was showing you, the denominator is about a million
there, too. And I am not quite sure how much of that is
going to be Rotarix or RotaTeq. And remember, in the US,
Rotarix is just not used. So even if you were to try to do
the study, you can’t really get the charts to review
RotaTeq, so depending on how the denominators for those two
vaccines work out, we are not quite sure, because the VSD
study was also approaching a denominator of about a
million. And they didn’t see anything.
So at the end of the day you may be still left
with, we don’t see anything here but our denominator is
still just right there. So I am not quite sure. If we
thought, if the working group thought that this was a
definitive study that would give us a definitive answer in
the United States, we may make that a choice number one and
say let’s just wait. This is what we have now, we are
going to continue to wait for the answers to come in and
adjudicate claims as they come in.
But given that we are not quite sure at the end
of waiting two years how those answers will actually help
us to go one way or another -- this is just full
transparency, that’s what our thinking is -- but we still
wanted to give you that option as a recommendation choice.
34
So those are the four choices that we thought you
want to consider. I guess at this point in time how do we
want to do this? Should we go around?
DR. HERR: Do we have any anticipation of any
change in vaccine production from the manufacturers, in the
sense that we anticipate that RotaTeq is not going to be as
available as it has been in the past? Because we have had
this with other vaccines where all of a sudden they are not
making it. Or, do we anticipate any change in purchase in
the sense that VFC authorization, does VFC purchase now
both RotaTeq and Rotarix?
Or do we have a preference of one versus the
other? In the sense of, if the predominant use in this
country is RotaTeq and the increased risk is primarily
through what we know so far from the Mexican study is
Rotarix, are there things that we could do purchase wise?
That we would have VFC authorize only RotaTeq purchase
versus Rotarix that would modify that while we wait for the
study?
If the makeup of the vaccine use in this country
stays the same, we’re not really going to see much, and we
shouldn’t see as much. And that might in many ways still
be a safer, responsible thing to do while we look at more
information.
MS. PRON: What is the safety thing?
35
DR. HERR: The Rotarix, by the studies, is a
little bit riskier vaccine. And it may be just because of
the data and what data information we don’t have.
DR. JOHANN-LIANG: Right. If Mexico and Brazil
actually -- the manufacturers compete for the country to
buy, and Rotarix just won out, that was all. But if
RotaTeq had won out, who knows what the data would be,
right? So I totally know what you are saying.
In answer to your question, number one, do we
know if there have been any shortages for either
secondarily? Not that I know of. Do you know, Tom, from
CDC?
DR. HERR: Not that I know of.
DR. JOHANN-LIANG: We have talked to the
rotavirus people at CDC pretty recently. I don’t think
they anticipate there is going to be any shortage issues.
But you are right, we don’t know. Maybe there is some
contamination with RotaTeq and then Rotarix is available
and Rotarix gets the big uptake. Anything is possible.
But right now we don’t know anything in the future.
Number two, to answer your question about do we
know whether either one is preferred to be used, RotaTeq
came before Rotarix and that is why it sort of stayed.
DR. EVANS: Market share.
DR. JOHANN-LIANG: But according to CDC, although
36
I am not really sure what the exact information source for
them to say, but they do think that Rotarix, the company
will try to be more competitive as far as pricing, et
cetera, and they will try to market it in this country
more, and that the uptake of Rotarix will go up.
I don’t know what the timeframe is, but the
market share right now is mainly all RotaTeq and a little
bit of Rotarix. But over time, it will come up. Rotarix
will come up. That is their feeling. But I don’t really
know. This is company, probably financial information that
we are not privy to, so we don’t really know.
DR. HERR: Wouldn’t a responsible thing now be
for us, while we study, to put more governmental preference
on purchase of the safer vaccine? I mean again, it is not
our purview, so to speak, here, because we are talking
about the table. But again, our responsibility here is to
look at facts in utilization and safety of the vaccine.
DR. JOHANN-LIANG: Right, but I guess the general
thinking behind this is that you have the background of
RotaShield. You have two different second generation
vaccines. And granted that they are different, a
reassortment, et cetera, and we do think that we have more
information on Rotarix, but, again, that is because of who
studied it and what the denominator was.
We don’t really know whether there is a
37
difference in safety between these two vaccines. The data
is what we have. It really depends on how many people you
study in what sort of a population. The study does not
assure us that RotaTeq is safer than Rotarix, or Rotarix is
safer than RotaTeq or anything like that. We just don’t
have enough data to say.
But given the background of RotaShield, given the
Guiding Principles, we thought the best thing to do is to
give presumption of causation. Not that there is causation
per se, but presumption of causation for second generation
rotavirus vaccines in general, and propose to put that on
the table, with a qualification saying that if you have a
child with a lymphoma, if you have a child that had an
adenovirus infection within the right time, that that is
really not a qualifier for presumption. Because that would
be much more likely as an event to an IS than a rotavirus
vaccine.
So we are not saying one vaccine is safer than
the other, we’re saying we are kind of looking at it in
total. Does that make sense to you?
MS. HOIBERG: My question is, we talk about how
if the shot aggravates a pre-existing condition. Yet here,
you are excluding pre-existing conditions, children with
pre-existing conditions you are excluding from really it
being a presumption of causation, if I am using that
38
correctly.
It says onset in a person with a pre-existing
condition, which causes lead to intussusception, such as
intestinal masses and cystic structures. Who is to say
that the vaccine didn’t aggravate that condition?
DR. JOHANN-LIANG: It is really important to
remember that when we put something on a table it is a
presumption of causation. We are just saying, without
going through all the litigation, someone comes in with
intussusception within this timeframe, they get the
presumption, unless it’s blah blah blah blah.
That doesn’t mean -- what you are talking about
is an aggravation. We are not defining what would be an
aggravation to the underlying disorder. I mean, that just
gets way too -- but if you have a case and let’s say the
person has an underlying disorder and you get the vaccine,
we can still look at that and do causation in fact. It’s
not like we can’t give them compensation. Does that make
sense?
This is just saying, when you are presuming
something, when you are saying okay, nothing else, we look
at it, it meets the facts, go, we have to have certain
rules of engagement. That’s what we are laying out here.
And as I told you, the numbers, the naturally occurring
intussusception as opposed to the possible small
39
attributable risk from second generation rotavirus, it
can’t be but that it’s these things, if somebody has a
clearly defined leading point, et cetera. That’s what
would define the qualification.
MS. JACOBS: Let me just add something. So
Congress’ original table that they created, it did the same
thing. They basically inserted exclusions of basically
pre-existing conditions. So it’s not like the program is
trying to do this de novo. So they have precedence for
that.
MR. JASON SMITH: The QAI, the first presumption
is the onset occurs after the third dose of the rotavirus
vaccine?
MS. SAINDON: No, that’s the opposite. That is
an exclusion.
MR. JASON SMITH: Exclusion, I’m sorry, I said it
the wrong way. So in other words that would not be a
presumption of causation.
DR. JOHANN-LIANG: The studies actually showed
that when you look at the total, there doesn’t seem to be
any difference in the incidence of intussusception of kids,
looking at the first year. So it looks like there may be a
small attributable increased risk for the first dose,
definitely. Maybe the second dose. We are just doing that
as a Guiding Principle, give the second dose.
40
But the third dose, the data really looks like it
may be protective, which is just to say that at the end of
the year everybody sort of ends up in the same place. So
for us to say that would be a presumption of causation,
would be really too much of a stretch. So that’s why it’s
not --
MR. JASON SMITH: It is? So you feel comfortable
that the data is supporting this exclusion from a
presumption --
DR. JOHANN-LIANG: Yes.
MR. JASON SMITH: Okay.
DR. JOHANN-LIANG: Dr. Smith, Candace? Are you
on the call?
DR. CANDACE SMITH: Hi.
DR. JOHANN-LIANG: On the West Coast. Do you
want to elaborate a little bit more on the third dose
issue? That is a question that came up.
DR. CANDACE SMITH: We have a study. Even from
the very beginning, the pre-marketing studies, it looks
like we were protective at the end of a year. You know, as
they did those pre-marketing studies they looked at the end
of a year and they were very protective against
intussusception. So as the post-marketing studies have
gone on, they have actually looked at first dose, second
dose, third dose, the risk with each one.
41
And what they noticed is that the risk is well
below one. Which means that it is protective by the third
dose. I think the most recent data is that you are at a
risk of .2, and a risk of one is, all things being equal,
there is no risk. So when you get to a risk of .2, that
means you are actually more likely to be protected against
intussusception than to get an intussusception after a
third dose.
And the reasoning behind that is, I guess the
best way to say it is the vaccine has kind of primed your
intestine and protected it against it. So that if you were
to have some sort of trigger for an intussusception, your
intestine is now primed and it is not going to have it. I
hope that makes sense.
MR. JASON SMITH: So it did show then, with each
administration of the vaccine the relative risk decreases
from first, second, third?
DR. CANDACE SMITH: Yes, we drop a lot. So I
think the Australian data was the most important. The
first dose was a relative risk of about five, the second
one was about 1.5, and the third one was .2.
DR. JOHANN-LIANG: So it would be very hard for
us to do that as a presumption. So that is why it would be
very hard for us to put that, just lump it all together.
We really struggle with this. We really think that this
42
is, under the Guiding Principles, the most generous way to
do it, including the second dose into the presumption, but
really making sure that we say, a third dose, if the
vaccine is actually protective, we don’t want to say that
is presumptively causal for intussusception.
DR. CANDACE SMITH: And I think it is important
to also say that just the natural intussusception, that
third dose time is the time when you should be at the
highest risk, the peak time for intussusception. So it is
really remarkable that you are seeing such a drop in the
people who receive their rotavirus vaccine, for that timing
of the third dose. So the science definitely points to the
third dose as protective.
DR. DOUGLAS: You noted a one in 100,000
occurrence. How does that match up against other injuries
in the table?
DR. JOHANN-LIANG: That’s a good question. Was
GBS, if you look at GBS, in the background, it is probably
one in 100,000. So that would be like a natural GBS
occurring. So that’s not on the table, but I am just
trying to think about the things, the claims that were
coming in. Thrombocytopenia, about one in 50,000, one in
40,000.
PARTICIPANT: So this is good. This is very
good.
43
DR. JOHANN-LIANG: This is very, very low risk.
We had a discussion about even mitochondrial incidents.
This is just diseases. We are talking about some things on
the table. And something in one in 4,000, that’s what he
was talking about. So we are talking about a very, very,
very small risk.
MR. DAVID KING: That would be 10 in a million
though, right?
DR. JOHANN-LIANG: Right.
MR. DAVID KING: And how many vaccines are
administered?
DR. JOHANN-LIANG: For rotavirus?
DR. CANDACE SMITH: About 30 million to date.
For RotaTeq, right?
DR. JOHANN-LIANG: 30 million, Candace, or less?
DR. CANDACE SMITH: Sorry, I didn’t hear that.
DR. JOHANN-LIANG: For RotaTeq.
(overlapping voices, off microphone)
DR. JOHANN-LIANG: 30 million. Flu is what, like
160 million last year, per year. I don’t want to give
numbers without actually having it in front of me. And I
have that data, so again, get that to me.
MR. DAVID KING: On the actual number of vaccines
that are given.
DR. JOHANN-LIANG: Distributed.
44
MR. DAVID KING: Distributed, right. We don’t
actually know how many are given. We have gone through
that, yes, I remember that.
MS. PRON: My question is, if we decide to go
with the proposed amendment and the study that comes out
suggests something different, which may be not for another
two years before we really get the final count and we
decide it’s really going to say what we want, we can change
it again, right?
DR. JOHANN-LIANG: Yes. But it is about two
years to go. So that’s a question. We could wait. If it
was a claim that is coming in a lot it may be really nice
to have a presumption so we could move cases along. But as
I have shown you, the experience, it is not a huge number
of claims.
So we could wait. That is one of the choices
that we have, wait for the study to come in. The other
side of that is that there is no assurance that that study
will be definitive, either. We may still be uncertain at
that point.
MR. DAVID KING: I know there’s not a great
number of claims. But based upon current data in terms of
the number of claims that we have, a third of those claims
are occurring after the third dose.
DR. JOHANN-LIANG: Third dose, yes.
45
MR. DAVID KING: Right. And we are excluding the
third dose here.
MS. PRON: That’s just for the automatic, you
know.
DR. JOHANN-LIANG: That’s a presumption of
causation.
MS. PRON: Presumption of causality. It doesn’t
mean that they are not going to get compensated down the
line.
MR. DAVID KING: Understood. But I would suspect
that if it isn’t on the table, the case would be made if
one were to say. they’d say, well, it’s not on the table.
I think it will be a lot harder for someone to make their
case if the table doesn’t reflect it. It makes it more
difficult for the petitioner.
And, since we are supposed to be, according to
the Guiding Principles, more aligned with weighing more
heavily on the petitioner’s side of the table than on the
other side of the table, that we would --
DR. JOHANN-LIANG: But you have to have some sort
of a -- you are not just going to, everybody who has an IS,
you are not going to be compensating. You want to try to
tease out who possibly is injured due to vaccine, and want
to be very generous about that. That’s, i.e., the
interval, the dose, the second dose, et cetera.
46
But if the vaccine really looks like it is
something that is protective against an adverse event
following that dose, it would really not be -- it doesn’t
make sense to say --
MR. DAVID KING: No, we might not know. The
research is not 100 percent complete. And we don’t have
the adjudication of these claims yet, so there is no
determination yet, I suspect, on a third of the claims
already that are saying that it happens after dose five.
DR. JOHANN-LIANG: Dose three?
MR. DAVID KING: Dose three, excuse me. So there
are questions. I am afraid to rush into decision-making
here without some lengthy understanding discussion related
around to things that answer, like, the number of vaccines.
The Vaccine Information Statement that currently exists
would be useful for us to be reviewing, so that we could
compare it in case there is anything here that might --
So there is a lot of information, I think, that
we would still need to have to have a conversation about,
before we rush to any judgment. So I am thinking more in
terms of cautiously moving forward, but I am not yet
prepared to throw a motion out on the table here on that,
because I think we should discuss this a little bit
further.
MS. DREW: I am in agreement with Dave, but I
47
need a little clarification on B, where we have onset
within one month after an infectious disease. Does that
mean any infectious disease? Does that mean a child who is
vaccinated while he’s got the sniffles isn’t going to be
covered under this? I don’t really know what that means.
DR. RUBIN: The qualification has the examples,
as I have talked about and discussed, that the main
infectious diseases were the viral diseases and the
bacterial enteritis, and also parasitic infections.
MS. DREW: But what it says is, an infectious
disease, including -- and then it goes on to say without
regard to whether the organism of the infectious disease is
known. The way I read that is, if the child has any
infectious disease including the sniffles, which we can
probably presume is a virus, when the child is immunized,
that is within a month, that child is not going to be
subject to the table. It is not going to be a table
injury.
DR. RUBIN: When a claim comes to our program,
the medical reviewers do review this. Most of the time all
of us are really, we would do a literature search. And
most of the literature doesn’t necessarily show a strong
association with just, as you call it, the sniffles.
MS. DREW: But that is what the statute is going
to say. Irrespective of what your review may show, this is
48
what the statute says. So maybe that needs to be reworked
and make it clear that you are talking about something
intestinal as opposed to what it says now. I’ve got a real
issue with that.
DR. JOHANN-LIANG: When you look at the
literature, mainly the one month comes from exactly what is
listed there, which is the antiviral disease, which
actually is not just enteric antiviral disease but can be a
systemic antiviral disease. Some of the bacterial
enteritis, as well as parasitic infestations of the gut,
basically. And they are acting like a lead point, which we
don’t really see in the US very much.
So if the concern is that the language is too
broad so that it may make things like viral infections,
upper respiratory tract infections as an alternate factor,
then that’s something we can try to -- yes, we are open to
that. We are talking about infectious diseases that really
we know as causal for intussusception, that is well known
to be causal for intussusception.
There is a lot of literature even on using
antibiotics could be intussusception association, or ear
infections. So those are not what we were thinking of as
we were listing the --
MS. DREW: Also the word, within one month. Is
this within a month of the first manifestation of an
49
enteric disease? Or within a month after it is over? This
is so vague that I can just see all kinds of litigation
being sparked by this, litigation that isn’t necessary if
you folks clarify it before you put it into the statute.
MS. WILLIAMS: This is Michelle Williams. Are
there additional studies other than the PRISM study? Are
there still post marketing studies going on?
DR. JOHANN-LIANG: My understanding is that VSD
study, which is a US study that was presented at ACIP in
2010, it is kind of closed. And they are either preparing
or have already prepared for publication. And the
denominator for that, again -- and it’s mainly RotaTeq,
because it is US-based -- the denominator for that is just
under a million.
They see nothing. There is no attributable risk
at all in the US to the RotaTeq vaccine. Now I don’t know,
because it is not published, but this is personal
communication with the CDC person. So that is pretty much
done. It is my understanding in the US.
There is probably other, outside the United
States ongoing, with surveillance, et cetera, particularly
in Australia. I think that there is an ongoing study in
Australia with rather than doing -- remember I told you the
Buttery study was really looking at intussusception
happening over the expected background from historical
50
background in different provinces of Australia.
The one that is ongoing, that’s my understanding,
is actually doing this more self controlled, which is
thought to be a better quality study. So the Australians
are ongoing. But in the US I believe, Michelle, the only
thing we have is the PRISM. And we wouldn’t have any
preliminary results until end of next year, at best.
MS. WILLIAMS: And you had said -- I’m trying to
get a timing question to go to Dave’s and Sherry’s
comments, trying to move forward but maybe get additional
information at the same time. You started your notice, you
are drafting your notice. And when would the notice have
to go in? If we were to vote on it, when would the notice
go in? Would we see that notice before it got published?
DR. JOHANN-LIANG: Sure.
DR. EVANS: You will vote and make a
recommendation to the Secretary, and that will be taken
under consideration with the Department, and then the
notice will be published. And, as everyone else will, you
will have public comment, a six-month period of public
comment in which it can further be amended. And it will be
in the form of a final report.
MS. WILLIAMS: That was my question. If we voted
now and then the Notice of Proposed Rulemaking would be
drafted. But if there was additional information that
51
Sherry and Dave think need to be elicited, that would be
able to be done at the same time? Or would that require a
new recommendation?
DR. EVANS: It can always be adjusted and
tweaked, but there wouldn’t be a formal -- at least we have
not done that in the past -- a formal reconsideration
before it is published. But again, there can always be
changes after it is published because that is the whole
purpose of public comment.
MS. WILLIAMS: Just to try to figure out if we
are kicking the can or if we are going to expand or if we
are going to delay, if there is additional information that
could be incorporated into the Notice of Proposed
Rulemaking as comments?
DR. JOHANN-LIANG: Right. The Notice of Proposed
Rulemaking, it will take us some time to get that draft
together even though we have started drafting it. It’s a
regulation. It has to go through multiple clearances
through the agencies. That’s going to all take time. 2012
is an election year, we have been told. So any rulemaking
will take time.
We don’t want to delay too much. But let’s say
that during the process of proposing to NPRM -- and we can
always make changes, of course. And then even when the
NPRM goes out, it goes out for six months for public
52
comment and everybody is free to comment. That’s what we
are supposed to do, the Secretary, and hearing.
MS. SAINDON: Just to clarify one other thing.
By law you have 90 days. So you do not need to --
MR. DAVID KING: I was going to get a
clarification on that from you, if I could. On the slide
it says at least 90 days. So do we have more than 90 days?
Or do we only have 90 days?
MS. SAINDON: I think we can cut it off at 90
days, because the Secretary has --
MR. DAVID KING: That doesn’t answer my question
actually, if we can cut it off at 90 days.
MS. SAINDON: 90 days, you have 90 days.
MR. DAVID KING: So the at least 90 days is an
incorrect statement on the slide?
DR. JACOBS: No. It says the Secretary has to
afford the ACCV at least 90 days. So if they afford you 90
days --
MR. DAVID KING: Then they can do what they want.
DR. JACOBS: Yes.
MR. DAVID KING: Thank you. Now I have the
understanding, thank you, perfect. So we would have till
March 9th? Is that accurate? Or because we do have 29
days in February --
DR. JOHANN-LIANG: I don’t know, we have to look
53
at the calendar. Is that including business days or
weekends?
DR. JACOBS: I guess not. 90 days is 90 days.
MR. DAVID KING: That’s what I would do, 90 days.
So we meet on March 8th, and on March 9th. So we would be
within the timeframe of the statute, to be able to give a
recommendation if we were to review this at the next
meeting, say. And it might be more than a 15-minute
conversation.
DR. EVANS: Your comfort level is what is
paramount. If you need additional time to consider this,
that’s fine.
DR. JOHANN-LIANG: And that’s your choice here.
If you’d like to review the proposal.
MR. DAVID KING: This is one man’s opinion,
though.
MS. PRON: At least in my understanding -- I need
clarification here if it’s not correct -- this is Ann Pron,
for the people on the phone. Currently rotavirus, there is
no table of injury for rotavirus. So in fact, by adding
this, at least we are helping some folks, some parents, to
move along quicker. But if we don’t add it, everyone has
to go through the long process. Am I correct?
DR. JOHANN-LIANG: Yes, that is correct.
MS. PRON: So it may be in the future, if more
54
data -- because right now the data for dose three is not
really meaningful. There is not really anything in their
research that showed that there is an association between
dose three and intussusception. In fact, it goes in
reverse is what they are saying. It is a decrease in
intussusception after dose three rather than an increase in
cases.
So that if we pass this, in some ways we are
erring on the side of helping families rather than setting
up obstacles. That’s my read. Is that accurate?
MR. DAVID KING: I think that is one
interpretation. But I think that we may also be impeding
if we move too quickly because of the wording that Sherry
has brought up, in terms of what specifically does that
mean. So I think that we may be creating a litigation
nightmare and dragging things out. But I do think that we
need to be sensitive, though, to the fact that nothing is
on the table.
So I have a couple of questions, then, that will
help me in my thinking here. One of the questions is, if
we were to not wait till the next meeting to do this, and
to do this today, what material difference would that make
to getting it onto the table, as opposed to waiting till
March 8th or 9th?
In terms of what is the real timeframe, is it
55
going to make any significant difference? Or is it still
going to be the same time period?
DR. JOHANN-LIANG: It is really unclear, because
the timing of clearances is really not in our control. But
I can tell you that you guys have a lot of work ahead of
you with IOM. We are working really hard to try to bring
stuff to you next year, so we have got a lot of work to do
to move things forward.
The idea behind this is to take a program that is
so much off table, and so as you heard yesterday there is a
lot of litigation involved, to try as best we can with the
current size, with the Guiding Principles in mind, to add
things to the table so that we could give presumption of
causation. The medical folks are all here for presumption
of causation. That will really cut down on the time clock,
and we want to move things forward.
So the idea of waiting is fine. That is one of
the choices that we have, because it really is up to your
recommendation as to what you want to do. But I think next
year, personally, we are going to be in a lot of time
crunch. I am not sure. This is off of IOM, and we have
these signals from outside of the US coming in. We should
try to bring this to you. But it is really up to you.
MS. WILLIAMS: Let me ask another timing
question, then. Would your Notice of Proposed Rulemaking
56
go in to start the clearance process before our next
meeting?
DR. JOHANN-LIANG: We would like to.
DR. EVANS: To add on to what Rosemary said, in a
shorter version, the IOM track is going to be thick, long,
wide, lots of things on it. We had the perhaps idealistic
notion that we could have a quick, narrow short track to
get this done, as separate, get it within the Department
and they could clear it sooner, and not be as involved as
we are facing with the other rulemaking. And we got the
agreement to do it that way, which is a little different.
Normally people like to lump things together and
just do it all at once. We said no, this is different,
this was not IOM, and we think this is much more condensed
and simplified. But, as a great philosopher once said,
nothing is ever simple. I think the questions raised today
are legitimate questions, if somehow we can come to some
agreement and some answers. But if this could go forward
sooner than later I think it is better.
DR. FEEMSTER: I have one question about the
data. One thing that I noticed, for RotaShield the rule
very specifically referred to rhesus-containing, they
really talked about the components of the vaccine. This
time it doesn’t. Really, the data is quite different.
There is some suggestion that we may or may not end up
57
finding a definitive signal as studies are ongoing,
particularly in the US, for RotaTeq.
Was there any thought about -- I am not saying
that we shouldn’t add this to the table -- but about being
specific about the vaccine components? Because if down the
line, the PRISM study doesn’t show a signal with RotaTeq,
for example and we may make a decision to change the rule.
But Rotarix -- I mean, they are both quite
different, and you could argue that they may act a little
bit differently in the gut. One is human-based, one is
bovine-based. I just wondered if that was something that
you did talk about, because it was so specific with
RotaShield.
DR. JOHANN-LIANG: That is a very good point.
DR. FEEMSTER: And the data, especially now that
I hear that the Buttery study was comparing historical
data, that really makes it less powerful in my mind, if we
are weighing the strength of evidence.
DR. JOHANN-LIANG: I have to tell you,
preliminary data, although nothing is published yet, of the
self-controlled, the better, it seems to be in line with
what they have already shown. It is not contradictory.
Yes, Dave, go ahead.
MR. DAVID KING: So --
DR. JOHANN-LIANG: This is in regards to her
58
query, right? Otherwise I am going to respond and then you
can say.
MR. DAVID KING: You are going to respond to the
query here?
DR. JOHANN-LIANG: Yes, are you responding to her
query?
MR. DAVID KING: No.
DR. JOHANN-LIANG: Can I just respond to it then?
You are absolutely right. We could do what we did before
with the RotaShield, which is, you leave the rotavirus
vaccine blank, and then add another row that specifically
says only for the RV1 or the human-based, whatever. Not
the bovine-based, but the human-based. We could do that.
But the struggle that we had was, because Rotarix
is underutilized in the US, although we don’t know what the
uptake will be, we don’t even have one claim for it
actually. So we decided that, let’s say that Rotarix,
RotaShield, that’s two of three vaccines already, why don’t
we just do the general characteristics? Again, applying
the general principle. We are trying to be overly generous
at every turn here.
DR. FEEMSTER: I can see that. It’s just there
seems to be such a differential at least. It seems like
the stronger data is associated with the bovine-based
vaccine. But I understand that as well.
59
DR. JOHANN-LIANG: You see it’s a lot of levels.
DR. FEEMSTER: It’s not easy.
MR. DAVID KING: So there is a consensus I think
that we want to do something because we should. The
question is on timing. But there may be a way to make the
timing happen. Could there be changes made to the proposal
now, as we are speaking, that incorporated the concerns
that Sherry raised?
In other words, can we change the wording of this
right here and do some things along that nature to tweak
this as we sit in this meeting, it changes it, and then we
might be able to give you something that you can move with
today?
DR. JOHANN-LIANG: I am not sure if time is going
to allow us to word something right now. If they vote to
move this forward, can we have them make comments to the --
MS. SAINDON: Yes, the law requires, we are
seeking your comments and your recommendations. So if your
recommendation is to move forward and incorporate as many
of your comments as we can reasonably do, that is a totally
reasonable recommendation.
MR. JASON SMITH: Dave, can I suggest along the
same lines -- and I am in complete agreement, I think
Sherry’s concerns are good ones. Could we possibly
recommend that we move forward, but ask the Secretary to
60
consider some of the concerns raised by Sherry so that it
doesn’t appear to be from a language standpoint overly
restrictive in terms of that Paragraph B?
DR. JOHANN-LIANG: And that is precisely why we
provided you with all the references that we use for each
qualification, so that you can actually take a look and see
what your thoughts are on the matter. So we really welcome
that. That is why we are asking.
But as far as recommending what you want to do,
if you are concerned that if you recommend to move this
forward now it has got to go exactly the way it is, it is
going to take a lot of time to get it to --
DR. HERR: You can’t change any words at all on
it.
DR. EVANS: No, of course you can. In other
words, specify the kinds of changes you would like to make.
DR. JOHANN-LIANG: I didn’t hear what Tom said.
DR. HERR: I was just, you were making the
statement, it has to go as it is.
DR. JOHANN-LIANG: No. The recommendation is to
say, we want to do the table change. And I think what I am
hearing relevant to this is, that we welcome, and that’s
why we provided you with every slide with the references,
et cetera.
MR. DAVID KING: Just so I understand, because I
61
don’t want a motion to get on the table and we all go down
the road with a motion that we think means something but it
means something else. So before we make those motions,
let’s very quickly make sure we understand what we are
talking about here.
Which is, if we were to recommend that we wanted
to go forward with the change to the table, could we in
that recommendation specifically state, subject to certain
changes in this, and then that would then be the
recommendation so that it would be the recommendation is
that we want some of these changes? Can that be done?
DR. EVANS: Yes. For example, the Commission
years ago voted to add GBS for tetanus vaccine and for the
Secretary to develop an Aids to Interpretation to
accurately identify cases of vaccine-related GBS. Well
that was not possible, and the Secretary decided not to add
GBS to the table. That was the ACCV’s recommendation. The
Secretary didn’t take it. So you can recommend --
MS. SAINDON: But your recommendations will be
included in the preamble to the Notice of Proposed
Rulemaking, and we take them very seriously. So we are
seeking your comments.
MS. WILLIAMS: I think Dave’s question is, will
the Notice of Proposed Rulemaking have this paragraph just
the way it is? Or will the Notice of Proposed Rulemaking
62
be changed to have the paragraph be changed?
DR. EVANS: It is likely to be changed, and it
may be changed in 100 percent the way that you all are
describing, or there may be variations on the theme. But
the point is, you are voting to both add something to the
table as well as comment and endorse changes to the Aids to
Interpretation that will describe the injury that is being
added to the table.
MR. DAVID KING: Which is not exactly the same
thing as making the actual change. Is that correct?
DR. EVANS: Yes, there are two things. You are
adding under the general category of rotavirus vaccines,
you are adding intussusception with an onset of zero to 21
days. That is the first recommendation. And then the
second would be pertaining to the Qualifications and Aids
to Interpretation.
DR. JOHANN-LIANG: I just want to add, though, if
we didn’t have the IOM things coming down the line, we may
have much more, just practically speaking, much more time.
But because we want to start tackling those things starting
the next ACCV meeting, as I told you in the beginning of
the slides, it would be helpful if you guys, for that
second motion, if there was some sort of a timeline that
you would bring your recommendations and suggestions and
comments to us.
63
So that we can try to do the NPRM, try to get
that out, at least before March. We can’t promise
anything, but we are really trying to move things forward.
Does that make sense? We don’t want to be just waiting.
It’s another way of saying that we really want to hear from
you and incorporate what you want to say to the NPRM. But
we do have timeframes here, for us to move forward.
MR. DAVID KING: There is a saying, though, haste
makes waste. Let us be careful.
DR. HERR: This really is simple. But in your
alternate underlying conditions, on your slide you thought
it was important enough and during your presentation, to
say inflammatory bowel disease. But it is not in the
statute recommendation changes. Should it be there?
DR. JOHANN-LIANG: The inflammatory bowel
disease, really to be complete. It is more adults that can
actually have something like intussusception, or bigger
people. Usually babies, babies at six months, really there
is no diagnosis of Crohn’s or ulcerative colitis. We
really geared it more towards that and that was the logic
behind it.
DR. HERR: I just thought, you thought enough of
it to put it on your slide.
DR. JOHANN-LIANG: I think she was trying to be
very comprehensive.
64
DR. HERR: Okay, that’s fine.
DR. DOUGLAS: But in terms of advocacy for
parents who are looking for remedy, the best move for them
would be to have this on the table.
DR. JOHANN-LIANG: We are always trying to see
what would be best. Because it will help the presumption
to move forward. We would be doing everything else the
same way we are doing right now. It will cut down on the
amount of time, but again, we really want to hear from you,
and this is really good, the discussion that we are having,
because there is a science and there is a policy, and then
there is the patient advocacy. And those all have to kind
of merge.
That’s what is very different about this, that
pure science will logically say, we wait. But the program
and what our goals are, is a little bit different than
that. It is more over-arching than that. So that is why
we have before you. If it was purely left up to science,
Dr. Tom, we would wait. Right? Absolutely.
DR. HERR: This is Tom Herr. I would like to
move that we approve it.
MS. PRON: I will second it.
MS. WILLIAMS: When you say I approve it, I don’t
know what it is.
MR. DAVID KING: Your motion is to approve
65
exactly --
DR. HERR: As distributed. With the underlying
assumption, a realization that the Secretary can change
this as she wants.
(overlapping voices)
DR. HERR: What we are doing is approving that we
would like to move forward on the issue. And the issue is
to make a table of injuries, to facilitate taking care of
the kids who have qualifications specified on the table.
And move it on.
If there are some things that are sort of in
between the need to be fixed, that can be done. And the
assumption is that the Secretary will do that. And if it
doesn’t, it will come back and people will argue about it,
and we will say we want more.
MR. DAVID KING: So there is a motion on the
table that was seconded. So we should vote on that.
(Whereupon, the motion to go forward with the
recommendations for a change to the Table, with the
understanding that comments have been made concerning
wording on the Aids and Qualifications, and with the hope
that the Secretary will re-read the wording and consider
the suggestions and comments made by the Commission, was
duly seconded and unanimously approved.)
DR. HERR: We don’t need the second motion based
66
on that.
DR. JOHANN-LIANG: That is perfect.
MR. JASON SMITH: Sherry, can I just add one
other suggestion, just as a general commentary to some of
the language?
MS. DREW: Please.
MR. JASON SMITH: With various other vaccines on
the table, and some of the injuries listed, there is a
section, Section C, for example, for vaccines containing
tetanus toxoid, vaccines containing wholesale pertussis,
Section C, where it is this generic language about any
acute complication, the sequelae of an illness, disability,
injury. Sort of along the lines that Sara suggested
before.
It seems that it is listed for every injury
except for this vaccine. If we can also suggest that the
Secretary consider that.
DR. JOHANN-LIANG: Very good. So we really look
forward to -- it is very helpful to have people’s comments,
second look, third look. Do you guys want to have a
general discussion about when you want to bring the
comments to the Secretary?
DR. EVANS: The comments are on the record. We
will look at the transcript.
DR. JOHANN-LIANG: There is nothing else?
67
DR. EVANS: There is nothing else we need to do.
MR. DAVID KING: The only thing is that when we
talk about the Vaccine Information Statements, I would
think that where they talk about when can you get it, or
who should not get it, or things like that, it should be
consistent with the wording that you have in here, with all
that. That is really what we are talking about.
DR. JOHANN-LIANG: Those are good comments.
MS. PRON: That would be for the next agenda, for
the next meeting maybe, to re-review the rotavirus? Is
that what you want to do?
MR. DAVID KING: No.
MS. DREW: No, the VIS.
MR. DAVID KING: Oh, the VIS, to review the VIS
on it?
MS. PRON: Because that is what you are making
reference to, the VIS now?
MR. DAVID KING: Yes, but that was more in terms
of the actual comments on it.
MS. PRON: But I don’t think we can add anything
unless we come here.
MS. DREW: We are running really late. So I
think we need to move on.
(Brief recess)
Agenda Item: Update on the Immunization Safety
68
Office (ISO), Centers for Disease Control and Prevention
(CDC) Vaccine Activities, Dr. Tom Shimabukuro, CDC
DR. SHIMABUKURO: In the interests of time, I
will move through my presentation fairly quickly. But
before I start I just want to acknowledge the contributions
of Dr. Jane Gidudu, who is my predecessor. I am pretty
sure that I will be here with everyone who is going to be
on ACCV three-year terms before I eventually rotate off as
well. But it is a pleasure to join you.
One update which I don’t have on my slides, I was
able to confirm yesterday that there is a clinical trial
going on. It is called Immune Responses in Adults to
Revaccination with Adacel 10 Years After Previous Dose. So
that work is underway, to look at that as a 10-year
booster.
I am going to cover some highlights from the
October ACIP meeting. The two I will is the Gardasil
safety review and the ACIP vote. And then just an update
on the VSD febrile seizure investigation. I would just
mention our role in supporting HRSA in the IOM-generated
task force, and then some recent selected publications.
There was a very extensive review of Gardasil
during the last October ACIP meeting, which was the lead in
to the vote on males. And the data sources for this review
were from pre-licensure studies, data from VAERS for both
69
males and females, data from vaccine rapid cycle analysis
in females, and then two manufacturer sponsored studies.
This is the Nordic long-term follow-up study, and the long
term study of Gardasil in adolescents.
That information was presented during a previous
ACIP meeting, and that is available. Actually this
presentation, this comprehensive review and those two
manufacturer sponsored studies, those presentations are
available on the ACIP website. I am actually not going to
go into details. I recommend you do look at the Gardasil
Safety Review by Julianne Gee, an epidemiologist in our
office. It is very thorough.
Before I get into this actual summary, I will
just say that there was data presented on males
specifically in Julianne’s presentation, because there was
a vote on males. And just going through some of the
numbers there is a total of 569 reports for males, and most
of these over 500 were post-licensure reports. So there
were a few pre-licensure reports in there.
The breakdown for serious and non-serious is
roughly 94 percent non-serious and six percent serious.
That is consistent with what we see in VAERS. If you
looked at what we call the MedDRA Preferred Terms -- so
these are codes we look at in VAERS, they are not mutually
exclusive, so an individual could be coded to have multiple
70
MedDRA Preferred Terms with a single report -- for serious
reports we did not see any pattern, which is reassuring.
There were two death reports, verified death
reports for males. One was a case of myocarditis in a 10-
year-old with no past medical history. The other was a
death in a 15-year-old, 25 days after vaccination, who had
a known congenital heart disease. This is all available on
the ACIP presentation, which is on line at the ACIP site.
So no new adverse event concerns or clinical patterns were
identified in this VAERS review.
The VSD rapid cycle analysis confirmed no
significant risks for pre-specified adverse events after
vaccination for females nine to 17 years and 18 to 26
years. You can see the pre-specified adverse events there.
Of note in the VSD rapid cycle analysis study, there was a
non statistically significant increase relative risk for
venous thromboembolism among nine to 17 year old females.
This study was just in females.
It is important to note that there was a pattern
that many of these cases had known risk factors for VTE,
like obesity, smoking, oral contraceptive use. Which is
not to say that the vaccine couldn’t have aggravated an
underlying condition. But there is further work in VSD to
assess this finding, to include looking at other vaccines
other than just HPV4.
71
Further evaluation of VTE post-vaccination is
ongoing through other studies. And the long-term follow up
of adolescents have not identified any safety concerns.
Those are from the two manufacturer studies.
So ACIP voted on vaccination for males, and their
vote was a routine recommendation for HPV4 for males 11 to
12 years. And this series can start as early as nine years
of age. Males age 13 to 21 years who have not been
vaccinated should be given catch up vaccination. And males
22 to 26 may be vaccinated, but there is not a
recommendation for routine use.
Moving on to the VSD febrile seizure
investigation, I know Jane briefed you on this
investigation. So the previous flu season, 2010, 2011, VSD
was monitoring nine outcomes, to include seizures. And
looking at inpatient and emergency department settings,
because the coding for outpatient seizures in VSD is not
really good. But the coding for inpatient, the positive
predictive value, is fairly high.
So VSD detected a possible increased risk of
febrile seizures on days zero to one, post vaccination, in
this age group, six to 59 months, who received a first dose
of TIV. After chart review and confirmation, it looked
like the risk was highest in the six to 23 month age group.
And most had received other vaccines, most commonly
72
pneumococcal conjugate vaccine and DTaP.
So the VSD investigators in CDC have presented
this a couple of times to ACIP. And what you see here on
this chart is actually the updated, what we think is going
to be the final updated results. This has been
provisionally accepted, this paper is provisionally
accepted to the journal Vaccine, and hopefully will be
published fairly soon.
What the investigators did for reasons which are
more into statistical methodology, they transitioned from
an age stratified analysis, to a statistical model. So
previously you may have seen these breakdowns -- six to 11
months, 12 to 23, 24 to 59 -- and seen the relative risks
in those age groups. And the decision was made to go with
a statistical model looking at the entire age group, but it
really didn’t change the bottom line.
As you can see here, there is a slight increased
risk in febrile seizures in this age interval for
inactivated influenza vaccine, without pneumococcal
conjugate vaccine. That is also plus or minus other
vaccines. And also a slight increased risk for PCV13,
without TIV, but with other vaccines.
But really the risk is highest when TIV was given
concomitantly with PCV13, and other vaccines, still in this
roughly 12 to 23 month age group, peaking at about 16
73
months of age at an attributable risk of 45 per 100,000.
If you flip that over that is about, in the age group, one
additional febrile seizure for every 2,000 to 3,000
vaccines administered.
So the recommendations after CDC and ACIP looked
at this, was that there are no changes in the immunization
schedule that were necessary at this time; giving
recommended childhood vaccines during a single health care
visit has important health benefits, and timely vaccination
can prevent influenza and pneumococcal disease and may
actually prevent febrile seizures from fevers from these
infections.
In our communications piece we also noted that
scientific evidence -- scientific studies have not shown
that fever reducing medicines like Tylenol or Motrin
prevent febrile seizures. So there is no recommendation to
use those prophylactically. And of course aspirin and
aspirin containing products should not be used to reduce
fever in children, because of the increase in Reye
Syndrome. There is a more comprehensive study underway in
the Vaccine Safety Datalink to assess febrile seizures in
general, and the contribution of other vaccines.
So I just want to point out that we have 16 ISO
staff that are currently supporting HRSA as members of this
task force that is reviewing the IOM report and generating
74
recommendations to update the Vaccine Injury Table.
A couple of quick notes on publications. We
recently had a publication come out, Duderstadt et al.,
which looked at data in the defense medical surveillance
system. The bottom line on this study was there was no
increased risk of diagnosed type I diabetes in any of the
study vaccines. And you can see those vaccines there.
Some of those are not really used that much in the civilian
world.
We had a study come out from the Vaccine Safety
Datalink on wheezing lower respiratory disease and
vaccination of premature infants. And there was no
evidence of increased wheezing lower respiratory disease
following routine vaccinations of premature infants.
And wheezing lower respiratory disease among non-
fragile premature infants appeared to be reduced for a few
weeks after live attenuated vaccinations. This did not
include LAIV. These live vaccines were MMR, varicella, OPV
and I think those are the live vaccines they looked at.
The top paper is just the HPV4 VSD rapid cycle
analysis paper that I discussed. And then the last paper,
Huang et al, was a survey of physicians looking into really
knowledge, attitudes and behaviors around the ACIP
recommendations to prevent injuries from post-vaccination
syncope.
75
And the take home message on this paper was that
few physicians are aware of the recommendations for post-
vaccination observation for syncope, and even fewer adhere
to them. So there is room for improvement in that arena.
That is all I have and I will be happy to answer questions
if you have any.
MS. DREW: Thank you. We are going to go out of
order a little bit on our agenda, and call for Dr. Salmon,
who needs to give his report, his update from the National
Vaccine Program Office as soon as possible. Dr. Salmon,
are you there?
Agenda Item: Update from the National Vaccine
Program Office (NVPO), Dr. Dan Salmon, NVPO
DR. SALMON: (off microphone) Yes, I am on the
line. Thank you for allowing me to go out of turn. I
appreciate it. The update that I give, I want to focus on
an upcoming NVAC, National Vaccine Advisory Committee
meeting February 7th and 8th.
PARTICIPANT: Can you speak a little louder?
DR. SALMON: Can you hear me okay?
PARTICIPANT: No.
MR. DAVID KING: Slowly and louder, please.
DR. SALMON: Let me try again. This is Dan
Salmon from the National Vaccine Program Office. The
update I would like to give is on our next NVAC meeting,
76
the National Vaccine Advisory Committee, which gives advice
to the Assistant Secretary for Health on vaccine policy.
Our next meeting is February 7th and 8th. Can you hear me
okay now?
MS. DREW: Yes, thank you.
DR. SALMON: Okay, good. There are a number of
items on the agenda which I can go through briefly but I
think one in particular which will be of interest to this
group. So the draft agenda which is still being finalized
includes topics such as the Adult Immunization Working
Group Health Care Personnel Influenza Vaccine Subgroup,
discussions of 317 funds and vaccine financing.
There will be updates from each of the agencies
and liaisons. There will also be international discussion
of immunizations in the international arena. And lastly,
not on the agenda but in terms of what is most important to
this group, we expect to file a report from the Vaccine
Safety Risk Assessment Working Group.
The ACCV has heard of this group before. This
was the working group that was set up for H1N1, and it
looked at all the safety data from the many systems that
were monitoring the safety throughout the vaccine program.
At this point they have been reviewing all of the end of
season analyses.
They have put together a final report, which will
77
be presented to and deliberated upon by the NVAC at the
February meeting. This will be a summary of what we know
about the 2009 H1N1 vaccine. Let me stop there, and I am
happy to answer any questions.
MS. DREW: No questions. Thank you Dr. Salmon.
DR. SALMON: Thank you.
MS. DREW: Is Dr. Barbara Mulach on the line?
DR. MULACH: Yes, I am here, and I am ready, if
you are ready for my update.
MS. DREW: Thank you. Just one second. You will
be giving an update on the National Institute of Allergy
and Infectious Diseases, National Institutes of Health and
Vaccine Activities. Thank you for waiting for us. We are
a little late, but please go ahead.
Agenda Item: Update on the National Institute of
Allergy and Infectious Diseases (NIAID), National
Institutes of Health (NIH) Vaccine Activities, Dr. Barbara
Mulach, NIAID, NIH
DR. MULACH: Sure. I just have one main thing
that I wanted to make sure that everyone was aware of. I
have spoken at previous ACCV meetings about the program
announcement that NIH and CDC co-sponsor. And that was
originally intended to expire in September, and then it was
extended through January.
In late November we were able to extend the
78
program announcement for three more years, which is very
exciting. And so just to remind you a little bit about
what this program announcement entails, it is called
Research to Advance Vaccine Safety. And the purpose is to
support research that will contribute to the overall
understanding of vaccine safety, wherever there are
scientific questions, where we don’t have enough
information.
I wasn’t available for the full morning session
but I am sure that one of the topics that was discussed as
part of the IOM discussion is that there still are a lot of
scientific questions that need to be addressed. And this
is one way in which scientists can propose ideas for how to
get more information in that area. So like I said, this is
the second iteration of that announcement.
It was sort of slow in getting the attention of
scientists at first, but I am very encouraged by the number
of people who have shown interest in seeing this new
announcement that came out in late November. I am very
hopeful we will be able to encourage people to look at some
of the ideas in the IOM report, and propose ways to try to
address those questions and get us more answers.
I will be happy to send the links, for those who
are interested in seeing the announcement. Again, we are
sharing it with the scientific community as well.
79
MS. DREW: Thank you. Does anyone have any
questions or want the links? Thank you, Dr. Mulach.
Lieutenant Valerie Marshall is here to give an update on
the Center for Biologics, Evaluation and Research, Food and
Drug Administration Vaccine Activities.
Agenda Item: Update on the Center for Biologics,
Evaluation and Research (CBER), Food and Drug
Administration (FDA) Vaccine Activities, Lt. Valerie
Marshall, CBER, FDA
LT. MARSHALL: Good morning. My name is
Lieutenant Valerie Marshall. I will replace Dr. Marion
Gruber as the FDA representative to this committee. Marion
Gruber is currently the Acting Director of the Office of
Vaccines, Research and Review. The former director, Dr.
Norman Baylor, has since retired from the position as
director.
Since the last ACCV update of September 2, 2011,
there were no new original biologic license applications
approved. However, there are several vaccines currently
under review, including a vaccine to prevent infants age 2
to 16 months of age from meningococcal disease types A, C,
Y and W134 [SIC -- w135?], a vaccine to prevent
pneumococcal disease in adults 50 years and older, and an
influenza vaccine containing four strains.
The Vaccine and Related Biological Products
80
Advisory Committee met on November 16, 2011 to discuss and
make recommendations on the safety and immunogenicity of
the pneumococcal 13-valent conjugate vaccine in adults,
aged 50 years and older, using an accelerated approval.
On September 16, 2011, the FDA and the National
Institutes of Health, the Institute for Allergy and
Infectious Diseases, held a public workshop entitled The
Development and Evaluation of Next Generation Smallpox
Vaccines. The purpose of the public workshop was to
identify and discuss the key issues related to the
development and evaluation of next generation smallpox
vaccines.
The workshop included presentations on the human
response to smallpox vaccines, and the development of
animal models for demonstration of effectiveness of next
generation smallpox vaccines. And that’s all I have for
FDA.
MS. DREW: Thank you very much, and welcome to
our meetings. We look forward to seeing you in the future.
LT. MARSHALL: Okay, thank you, my pleasure.
MS. DREW: That ends our presentations for the
day. Our next agenda item is the nomination and election
of a new Chair and Vice Chair for the Commission.
Agenda Item: Nomination/Election of New Chair and
Vice Chair, Ms. Sherry Drew, Chair
81
MS. DREW: Annie, do you have paper for us?
Paper ballots? I am not exactly sure how you want to
proceed with this. In the past we have had nominations
made and then just, if there was more than one nomination
we just made a secret vote. I don’t know if it will come
to that or not, but I am wondering if we could have
nominations for the Vice Chair now.
MS. HOIBERG: I would like to nominate Michelle
Williams.
DR. DOUGLAS: I would like to nominate Kristen.
MS. DREW: I don’t know if you want to say
anything. Hopefully the two nominees will be present for
most of the meetings. That’s probably the biggest
qualification. Do you want to say anything?
DR. FEEMSTER: I would be honored to serve as
Vice Chair and do plan to attend all upcoming meetings and
to work with the Chair to help make sure that we discuss
all that needs to be discussed and facilitate a smooth
meeting.
MS. DREW: Thank you. Michelle?
MS. WILLIAMS: The same. Top that. If asked to
serve I would be pleased to serve, and I do plan to attend
all the meetings.
MS. DREW: All right. Now we are looking for
nominees for the Chair.
82
MS. HOIBERG: Dave King.
MS. DREW: Second?
(Seconded)
MS. DREW: Any other nominations? I think that
one is easy. And I don’t think we need a secret ballot,
given we have only one nominee. We still have to vote, but
I thought we could do a show of hands. Show of hands for
Dave?
(Show of hands -- unanimous.)
MS. DREW: Dave has been elected unanimously the
new Chair of the Commission. I will turn this over to you
in a minute. If you want to just write down Michelle or
Kristen.
PARTICIPANT: Do we have the same length of time
of service spanning? Are we on the same term?
MS. DREW: You serve for a year, or however long
you choose to serve. You just have to be elected. There
isn’t any real term.
(Paper ballots collected and tabulated)
MS. DREW: Michelle has been elected our Vice
Chair.
MS. WILLIAMS: And may I say it was an honor to
run against Kristen a worthy honor.
Agenda Item: Future Agenda Items, Ms. Sherry
Drew, Chair
83
MS. DREW: I am still Chair here, and we are
looking for future agenda items now. Tom brought up a
subject yesterday, the packaging of vaccines, there should
also be something on the label. I think that needs some
further discussion. And I don’t even know who might
address that.
DR. EVANS: Well, we will work on it. It is
certainly an FDA issue. Also this issue of a CDC safety,
but also has some -- we will work with our colleagues on
that.
MS. DREW: Okay. Is there anything --
MS. PRON: It looks like we need something about
the VIS for rotavirus, possibly.
MS. DREW: Possibly the VIS for rotavirus.
MR. DAVID KING: Right. We need to determine
whether or not -- so the question I have on that, because I
do think that it needs to be reviewed, is, is it premature
to review it yet, though, if we don’t have it on the table?
So I don’t know if it is necessary for the next meeting or
not. I guess we need to figure that out.
MS. PRON: And we need to have an ongoing list of
things that will need to come up, even if it is not at the
next meeting.
MR. DAVID KING: I will do that. I’ll have that.
(laughs)
84
MS. WILLIAMS: There is no reason why it couldn’t
be included in the packet, even if we didn’t have --
MR. DAVID KING: I would agree. That’s fair.
DR. DOUGLAS(?): Most of the concerns are not
things that would be on the VIS. Most of the kind of
background concerns with the wording and the injury table,
that would not be on the VIS.
MR. DAVID KING: The future science meeting. Are
we going to have a report from them at the next meeting?
Michelle? Will there be a future science meeting report at
the next meeting?
MS. WILLIAMS: Yes, we can do that.
MS. DREW: All right, future science on the next
agenda.
MR. DAVID KING: There was one yesterday, wasn’t
there?
MS. WILLIAMS: That I didn’t attend.
(overlapping voices)
MS. DREW: I think now we need volunteers for the
agenda workgroup committee. Dave and Michelle will be on
it automatically. Probably we need one or two more folks
to meet once or twice prior to the next meeting to clarify
the agenda. Kristen? All right, Kristen will be on the
agenda meeting. Anybody else?
MS. PRON: I’m not sure how easy it will be for
85
me to call in. If it’s not hard, I will do it.
MR. DAVID KING: So why don’t we invite you, and
if you can make it, you will.
MS. DREW: And perhaps one of the new people
might even volunteer after they have been sworn in. They
could be drafted at that point.
MS. PRON: May I suggest another item then, for
the ongoing list on the agenda which we said from the
minutes? And I said it, but I wasn’t sure, because we were
all sort of talking at once. But injection practices,
changes to injection practices, recommendations about
changes to injection practices from the shoulder injury
reports that we had.
That was a carryover from the minutes from the
last time that we said we would talk about it, put it in as
an agenda item. But I don’t think we talked about it.
MS. DREW: Okay.
MR. SMITH: Maybe we could fold it into that
general topic during the CDC presentation, about this
concept of 15 minutes after the vaccination administration,
and if it is there to go ahead and try to educate more
about the importance of doing that, because of syncope. At
some point in the future, probably not the next meeting.
MS. PRON: Follow up to that research study that
you mentioned.
86
DR. HERR: We are currently doing analysis on
vaccine errors or administration injuries. Would you be
interested in just seeing the actual data on that? Or is
this more of an outreach? Are you more interested in
outreach and education to vaccinators and how to give
proper injections?
MS. PRON: I think that is an issue. That seems
to have come up in your study that the ACIP recommendation
hasn’t been implemented.
DR. SHIMABUKURO: You are talking about the
server paper?
MS. PRON: Yes. And the syncope issue.
DR. SHIMABUKURO: The way this works, this goes
through the ACIP General Recommendations Workgroup. And I
am actually on that workgroup. And this subject has come
up from time to time and there was no big light bulb that
went on with the servers so far, but that is certainly
something that we can pursue because that is recent
information.
Syncope they have discussed before. And as I
understand it, when you start making recommendations for
doing things it becomes a standard of care. And when it
becomes a standard of care, then it becomes possibly
something that involves litigation. So they are careful
about how prescriptive they are about how long and what you
87
are supposed to do, et cetera.
But this is something that is discussed.
Everyone is aware that there is certainly a risk in some
children and adults, of having syncope after vaccination.
It’s something that we can certainly bring back to the
General Recs Workgroup and just see what their current
thinking is, as far as this issue.
MS. WILLIAMS: Despite being a lawyer, I
recognize that it does become a standard of care. And then
ensuing civil litigation on a malpractice front. But that
is not our concern. Our concern is patient safety.
MS. SAINDON: In fact, the vaccine program covers
both vaccine administrators and manufacturers. So even if
it is the standard of care, the requirement would be that
they come to the VICP. So I think it is absolutely within
the purview.
DR. EVANS: This has been pointed out.
MS. PRON: Well, we have already compensated for
that, right?
DR. EVANS: And we have compensated, both
injection injuries as well as things like post-injection
syncope.
MS. WILLIAMS: Why shouldn’t it be a standard of
care?
DR. EVANS: And the practicalities of 15 minutes
88
in a busy clinic where there are very few places to wait
and so on. It’s a lot easier said than done when you put
it in a recommendation. So again, we will see what the
latest thinking is at the workgroup.
MS. HOIBERG: That goes back to what I have said
that the major problem is that the vaccines aren’t given
the respect that they deserve. They are given out just
really willy-nilly. And so especially with the flu vaccine
and all, I feel like there needs to be a step back and a
re-education of the practitioners and the people who are
giving out the vaccines, to be like, hey, listen, you need
to take care.
You are injecting something foreign into a body
and you don’t know how they are going to react, whether
they are going to faint, whether they are going to have a -
- you have got to be careful how you give it. They are not
careful. And so I think that re-education is something
that is very necessary.
DR. DOUGLAS: When I was an educator of the
initial practitioners, we take it very seriously. And
during my first meeting I noted that the large injuries
that come when you inject way up here, and my thought was,
no one in life has ever been taught to inject way up there.
So I just reiterated that we are educating properly initial
practitioners.
89
I know the older I get and the more gray hair I
have, the more babyish they look. And they look like
absolute children. But they graduate at 21 years old, and
professionals with a license. And we can’t call them
babies or honey or sweetie any more. (laughter)
And I have run clinics in malls and I have run
clinics in storefronts. And I have run clinics in
incredibly busy clinics and on military bases. We are
mindful. We have our little section with the little seats.
Especially even what I have learned here, just to reinforce
for me that if you shoot a teenager, they are going to drop
like a stone.
On that side of the table it is not a void, that
we are preparing people who must take a license, and they
must know. And so we are working very hard on that end.
MS. DREW: Any more future agenda items? Can we
go to public comment? Operator, do you have anybody
waiting for public comment?
Agenda Item: Public Comment
OPERATOR: We are showing no public comments at
this time.
MS. DREW: Thank you, the public comments session
is done. I think the meeting is complete.
DR. EVANS: What I wanted to do is just to
reflect on the sad fact that we are saying goodbye to three
90
people who have been part of the ACCV family for the last
three years, and I know at times probably they were going
to be part of the family for several generations -- Tom,
Sara and Sherry.
I was wondering if any of you would like to give
us some parting thoughts, as you sail off, ride off.
DR. HERR: It’s been a real honor and it’s been
an education to be here. I came in with certain
expectations and certain ideas about things. You learn,
you modify. So it’s important, it has been a growth in my
being in education. It has been well worth it.
And seeing people who work hard for this, and for
the kids and now adults in all phases, whether they be as
parents or whether they be as attorneys trying to fight for
them, or mobilizing the Justice Department, and Rosemary,
the things that they do to try to make things straight and
keep things in order.
It is a daunting task. As well as Geoff, trying
to keep all of us organized and keep himself in his job.
It is hard not being able to always realize what you are
trying to do and be fair to everybody. But it has been
something I have appreciated. Thank you very much.
MS. DREW: I agree with Tom. It has been an
education. I have always tried as an attorney to see both
sides to every issue. Here I have seen there has been at
91
least 10 sides to every issue. I have enjoyed working with
the people here. I have made some very good friends, and I
thank you for bringing me on, Geoff. I will miss you guys.
MS. HOIBERG: It’s been fun. Very educational.
Just keep up the work.
DR. EVANS: Well, it’s auf wiedersehen, it’s not
goodbye. But there are various ways that you can help us,
and please stay in touch with the program. And maybe we
will have televideo, tele meetings in the future and you
can always, if you have the time, tune in.
You are one of the select few that has a
reasonably good understanding of what this is all about,
and a reasonably good understanding is quite a lot to say.
Because there is a lot to understand about this program and
its ins and outs and so on.
So when you hear someone make a comment about the
compensation program from what they have heard or read in
the paper, whatever, you have this insight. It will serve
us, as you can be our ambassador to try to help people
understand what it is we are trying to do, and trying to do
the best we can at it.
I want to particularly thank Annie. Give Annie a
round of applause. She really has been just great getting
everything together. She really singlehandedly has put all
this together with a smile on her face.
92
We have the business to adjourn and we also have
business after we adjourn.
Agenda Item: Adjournment of the ACCV December
Quarterly Meeting
MS. DREW: Do I hear a motion?
(Motion to adjourn)
MS. DREW: Do I hear a second?
(Seconded)
MS. DREW: The meeting is adjourned, I will bang
the hammer for the last time.
(Whereupon, at 11:45 p.m., the meeting was
adjourned.)
